INTRODUCTORY. 


HE  United  States  Electric  Lighting  Company  was  organized  in  1878,  and  was 


T among  the  first  in  this  country  to  undertake  the  development  and  introduc- 
tion of  the  Electric  Light  for  purposes  of  practical  illumination.  The  Weston 
Electric  Light  Company,  which  is  now  owned  by  this  company  and  under  the 
same  management,  was  organized  a year  earlier,  and  several  of  the  inventors 
and  electricians  who  are  now  employed  by  the  United  States  Company,  and  whose 
inventions  and  patents  have  become  its  property,  had  done  a large  amount  of  valu- 
able preliminary  work  long  before  the  organization  of  either  company. 

W'ithin  the  past  few  years  lighting  by  electricity  has  grown  from  a doubtful  experi- 
ment into  an  established  system  of  illumination,  in  large  and  rapidly  increasing 
practical  use  ; and  in  the  work  by  which  this  result  has  been  accomplished  this 
company  has  taken  an  active  part.  Having  abundant  capital,  it  has  been  able  to 
employ  inventors  and  electricians  of  the  highest  ability,  to  furnish  them  with  extraor- 
dinary facilities  for  experimental  work  and  investigation,  to  secure  the  control  of 
important  inventions  made  by  other  inventors,  and  to  provide  extensive  manufactur- 
ing facilities  for  constructing  its  apparatus  in  the  most  perfect  and  economical  manner. 

Mr.  Weston,  Mr.  Maxi.M,  and  Professor  P'armer  are  the  principal  electricians 
of  the  company,  and  the  apparatus  which  it  manufactures  has,  for  the  most  part,  been 
invented  by  them.  Other  inventors  and  electricians,  of  well-recognized  ability,  have 
also  been  employed,  and  valuable  outstanding  patents  have  been  purchased  from  time 


to  time. 


The  ablest  counsel  and  experts  in  the  country  have  been  employed  by  the  Com- 
pany to  take  charge  of  all  patent  matters  relating  to  its  business,  and  great  pains 
have  been  taken,  not  only  to  thoroughly  protect  by  patents  the  work  of  its  own 
inventors,  but  to  carefully  avoid  infringement  of  the  rights  of  others. 

The  company  noiv  ozons  or  controls  more  than  a hundred  atid  fifty  patents,  and  is 
constantly  adding  to  this  number  as  its  inventors  make  further  imijrovements.  These

THE  UNITED  STATES  ELECTRIC  LIGHTING  CO. 


relate  chiefly  to  the  electric  light,  electro-plating,  and  electrical  transmission  of  power, 
and  cover  the  most  important  contributions  made  to  the  progress  of  these  applications 
of  electricit}’  during  the  past  twenty  years. 

As  is  well  known,  there  are  two  principal  systems  of  lighting  by  electricity  — the 
voltaic  arc  system  and  the  incandescent  system.  While  other  companies  have  given 
their  exclusive  attention  to  one  or  the  other  of  these  two  systems,  this  company  has 
undertaken  the  development  of  both,  believing  that  the  greatest  advantages  would  be 
secured  by  working  the  two  together.  The  arc  light  is  especially  adapted  for  light- 
ing large  spaces  where  a great  amount  of  light  is  required,  but  is  not  suitable  for 
general  interior  illumination.  The  incandescent  light  is  especially  adapted  for  interior 
lighting,  as  it  admits  of  more  convenient  division  and  distribution;  but  it  is  greatly 
inferior  to  the  arc  light  in  economy  for  lighti  ng  large  spaces.  In  many  cases  the  best 
results  can  be  obtained  only  b}’  a combination  of  the  two  systems. 

The  W eston  arc  system  and  the  incandescent  system,  comprising  the  Maxim  incan- 
descent lamp  and  the  W'eston  machine,  which  have  been  adopted  by  the  company, 
have  long  since  passed  the  experimental  stage,  and  are  in  extensive  practical  use 
both  in  this  country  and  abroad.  They  have  received  the  highest  commendations, 
both  from  eminent  scientific  men  and  from  practical  users,  and  the  large  and  rapidly 
increasing  demand  for  apparatus  for  lighting  by  these  systems  is  the  most  satisfactory 
evidence  of  the  estimation  in  which  they  are  held  by  the  public. 

It  has  been  tho  policy  of  the  compan\'  to  spare  no  trouble  or  expense  in  securing 
the  best  forms  of  dynamo-machines,  electric  lamps,  and  other  apparatus,  and  in  per- 
fecting them  in  all  their  details.  Very  important  improvements  have  recently  been 
made,  bj'  which  greater  simplicity  of  construction,  and  higher  efficiency  and  reliabil- 
ity in  operation  have  been  secured.  As  such  apparatus  has  to  be  used,  for  the  most 
part,  by  persons  having  little  or  no  practical  knowledge  of  electricity,  it  has  been  the 
aim  of  the  company  to  make  its  apparatus  strong  and  simple  in  construction,  and  self- 
regulating, as  far  as  possible,  in  operation,  so  that  it  can  be  operated  without  difficulty 
by  any  person  with  the  most  ordinary  knowledge  of  mechanics.  In  this  respect,  as 
well  as  in  efficiency,  economy,  and  reliability  in  operation,  and  in  the  color  and  steadi- 
ness of  the  light  produced,  these  systems  of  lighting  are  confidently  believed  to  be  far 
superior  to  any  other  now  before  the  public. 

In  addition  to  its  principal  business  of  manufacturing  electric  lighting  apparatus, 
the  company  does  a very  large  business  in  electro-depositing  apparatus.  This  branch 
of  the  business  was  established  by  the  W'eston  Company,  and  has  been  very  suc- 
cessful. The  W'eston  electro-depositing  machine  has  gone  more  largel)'^  into  use  than 
any  other  in  the  market,  and  has  in  all  cases  given  the  most  satisfactory  results. 

hdectric  motors  and  various  forms  of  special  apparatus,  and  instruments  for  use 
with  large  currents,  are  also  manufactured  by  the  company. 

Since  its  acquisition  of  the  W'eston  factory  at  Newark,  N.  J.,  the  company  has 
concentrated  its  manufacturing  business  there.  The  capacity  of  this  factory  has  been 
more  than  cpiadrupled  during  the  past  year,  and  it  has  been  fitted  up  in  the  most 
thorough  manner  with  the  best  modern  tools  and  machinery.  It  is  one  of  the  largest

and  best  appointed  factories  in  the  country  devoted  to  electrical  work.  A large 
force  of  skilled  workmen  is  employed,  many  of  whom  have  been  with  the  company 
for  a long  time,  and  have  been  thoroughly  trained  in  the  manufacture  of  its  apparatus. 
Only  the  best  materials  are  used,  and  great  precautions  are  taken  to  insure  the  most 
accurate  mechanical  and  electrical  work. 

Various  subsidiary  or  local  companies  have  been  organized  in  different  parts  of 
the  country,  under  licenses  from  this  company,  and  all  are  in  successful  operation. 
Among  these  are  the  New  England  Weston  Electric  Light  Company,  of  Boston, 
Mass.;  The  Rhode  Island  Electric  Light  Company,  of  Providence,  R.  I.;  The  Con- 
necticut P'lectric  Light  Company,  of  New  Haven,  Conn.;  The  United  States  Illumi- 
nating Company,  of  New- York  City;  The  Newark  Electric  Light  and  Power  Company, 
of  Newark,  N.  J.;  The  Maxim  Pdectric  Light  and  Power  Company,  of  Philadelphia; 
The  Rochester  Electric  Light  Company,  of  Rochester,  N.  Y. ; The  United  States 
Electric  Illuminating  Company,  of  Charleston,  S.  C. ; The  Citizens’  Electric  Light 
Company,  of  Toledo,  O. ; The  Cincinnati  Electric  Light  Company  ; The  Swift  Elec- 
tric Light  Company,  of  East  Saginaw,  Mich.;  The  St.  Paul  Electric  Light  and  Power 
Company,  of  St.  Paul,  Minn.;  The  Racine  Electric  Light  and  Power  Company,  of 
Racine,  Wis.,  and  many  others. 

These  companies  are  using  and  introducing  the  apparatus  manufactured  by  the 
-parent  company,  and  many  of  them  are  doing  a large  business  in  furnishing  lights  on 


rental  from  central  stations. 


ADVANTAGES  OF  THE  ARC  SYSTEM. 


’"’'IIE  superiority  of  the  Arc  light  over  all  other  systems  of  illumination  for  use  in 


1.  places  where  a large  amount  of  light  is  required,  has  been  thoroughly  demon- 
strated by  experience,  and  is  now  generally  well  recognized. 

Fu'st.  It  is  the  cheapest  artificial  light  known.  This  has  been  shown  both  by 
scientific  tests  and  by  the  experience  of  practical  users  given  in  the  testimonials  which 
we  publish  farther  on. 

Second.  It  is  the  safest  light  known,  being  wholly  free  from  all  danger  of  explosion, 
leakage,  use  of  matches,  etc.,  incident  to  gas,  oil,  and  other  systems  of  lighting.  The 
underwriters  throughout  the  country  have  made  a careful  examination  of  the  subject, 
and  have  in  all  cases  concluded  that  lighting  by  this  system  is  free  from  danger,  when 
the  apparatus  is  properly  constructed  and  erected.  The  New  York  Board  of  P'ire 
Underwriters  has  adopted  regulations  for  the  erection  of  plants,  with  which  we  care- 
fully comply. 

Third.  It  is  a pure  zuhite  light,  in  character  closely  resembling  sunlight.  All 
colors  appear  precisely  the  same  by  this  light  as  by  daylight.  This  is  a point  of  great 


THE  UNITED  STATES  ELECTRIC  LIGHTING  CO. 


7 


importance  where  artificial  light  is  used  in  factories,  stores,  dye-houses,  and  other 
places  in  which  it  is  desirable  to  distinguish  colors. 

Fourth.  It  is  an  agreeable  and  zuholesome  light.  A single  gas-burner  consumes  as 
much  oxygen  as  is  required  by  five  or  six  persons  for  respiration,  and  the  noxious 
gases  and  great  amount  of  heat  evolved  by  oil  and  gas  lights  are  disagreeable  and 
deleterious  to  health.  The  electric  light  does  not  depend  on  combustion  for  its 
illuminating  effects,  and,  accordingly,  does  not  vitiate  the  air,  and  the  amount  of  heat 
produced  is  extremely  small.  The  light  produced  by  the  Weston  arc  system  is 
remarkably  steady,  free  from  flickering,  and  is  soft  and  agreeable  to  the  eye. 

Fifth.  The  iuimense  quantity  of  light  which  can  readily  be  produced  by  the  arc 
system  renders  it  possible  to  obtain  a perfect  general  illumination  of  a workshop, 
store,  or  other  large  space  which  is  not  economically  attainable  by  any  other  system 
of  lighting.  This  is  of  great  importance  in  manufacturing  establishments  where  night 
work  is  necessary,  as  the  work  can  be  carried  on  with  almost  as  much  facility  by 
the  electric  light  as  by  daylight. 

The  arc  system  is  especially  adapted  for  lighting  streets,  public  squares,  parks, 
docks,  and  other  out-of-door  places,  and  for  lighting  large  interior  spaces,  such  as 
factories,  mills,  foundries,  mines,  warehouses,  stores,  public  halls,  railway  stations, 
hotel  offices,  tunnels,  and  the  like.  Although  it  is  not  suitable  for  general  interior 
illumination  where  only  a comparatively  small  amount  of  light  is  required,  the  arc 
light  is,  within  its  proper  field,  far  superior  to  all  its  competitors.  With  improve- 
ments in  apparatus  the  field  of  the  arc  light  is  constantly  expanding.  The  steady  and 
reliable  Weston  arc  lights  are  now  in  common  use  both  in  this  country  and  abroad, 
in  places  where  the  flickering  and  uncertain  arc  lights  of  two  or  three  years  ago 
would  not  be  tolerated,  and  are  giving  the  most  satisfactory  results. 


THE  WESTON  ARC  SYSTEM. 


The  Weston  Arc  System  differs  from  other  arc  systems  now  in  use,  not  only  in 
the  construction  of  the  apparatus,  but  in  the  character  of  the  current  used  and  in 
the  quality  of  the  light  produced.  The  lamps  are  adjusted  to  work  with  a shorter  arc 
or  separation  between  the  carbon  points,  and  the  machines  are  constructed  to  generate 
a continuous  current  of  low'er  electro-motive  force  and  greater  quantity  than  in  other 
systems.  This  not  only  obviates  the  danger  of  accident  to  persons  using  the  appa- 
ratus, but  renders  the  light  produced  of  better  quality  and  of  greater  quantity  for  a 
given  expenditure  of  power.  While  numerous  fatal  accidents  have  occurred  from  the 
use  of  machines  producing  an  intermittent  or  pulsating  current  of  very  high  electro- 
motive force,  710  person  has  ever  beeii  m any  way  injured  by  the  curroit  f7-077i  a Weston 
Machific.  This  remarkaMe  immunity  from  accident  is  not  by  any  means  fortuitous. 


s 


THE  UNITED  STATES  ELECTRIC  LIGHTING  CO. 


but  is  due  to  the  construction  of  the  apparatus  and  the  character  of  the  current  used 
in  tlie  Weston  system.  The  electro-motive  force  of  the  current,  even  with  a very 
large  number  of  lights  in  circuit,  is  too  low  to  permit  it  to  injuriously  affect  any  per- 
son accidentally  coming  into  contact  with  the  conductors,  and  the  current  is  continu- 
ous and  entirely  free  from  the  pulsations  to  which  the  disastrous  effects  of  the  current 
upon  the  person  injured  have  been  largely  due  in  such  accidents  as  have  occurred 
with  other  systems.  With  our  larger  machines  we  have  adopted  additional  precau- 
tions, in  thoroughly  insulating  all  parts  which  have  to  be  handled,  and  we  believe  that 
the  entire  safet}'  of  the  Weston  system  will  commend  itself  as  by  no  means  an  unim- 
portant advantage. 

The  flickering  due  to  slight  impurities  in  the  carbons,  which  is  so  noticeable  in 
long  arc  systems,  is  almost  entirely  obviated  by  using  a short  arc,  and  the  color  and 
quality  of  the  light  are  greatly  improved.  The  light  is  free  from  the  excess  of  blue 
and  violet  rays  so  noticeable  in  most  other  systems,  and  which  are  so  disagreeable 
and  tr)-ing  to  the  eyes,  and  the  light  is  much  more  diffusive. 

The  extreme  delicacy  of  the  feeding  mechanism  in  the  lamps,  and  the  purity  and 
uniformity  of  the  Weston  carbons,  render  the  light  remarkably  steady,  and  the  extra- 
ordinary efficiency  of  the  machine  secures  the  highest  degree  of  economy. 

In  addition  to  the  machine  and  the  lamps,  the  Weston  arc  system  comprises 
various  auxiliary  or  supplementary  devices,  such  as  regulators,  indicators,  cut-off 
boxes,  switches,  and  fixtures,  which  add  greatly  to  its  convenience  and  reliability. 

THE  WESTON  DYNAMO-ELECTRIC  MACHINE. 

mechanical  and  electrical  details  of  the  Weston  dynamo-electric  machine  have 
J-  been  very  carefully  studied,  and  we  believe  it  is  unrivalled  in  efficiency,  simplicity 
of  construction,  strength,  durability,  the  case  with  zuhich  it  can  be  repaired  in  case  of 
accidents,  and  excellence  of  zvorkmanship  and  materials.  We  in\'ite  a critical  examina- 
tion and  comparison  of  this  machine  with  any  other,  by  skilled  mechanics,  or  other 
persons  conversant  with  the  requirements  of  the  art.  It  is  beyond  doubt  the  most 
symmetrical,  substantial,  and  efficient  machine  in  the  market. 

The  general  construction  of  this  machine  is  shown  by  the  cut  on  the  opposite 
page.  The  field  magnets  are  placed  in  a horizontal  position  on  each  side  of  the 
armature,  and  their  cores,  pole-pieces  and  yoke-plates  form  a rectangle  of  cast-iron 
which  serves  as  the  frame  of  the  machine.  The  yoke-plates  at  each  end  are  carried 
down  so  as  to  form  feet,  which  support  the  machine,  and  the  supports  for  the  arma- 
ture bearings  are  cast  in  one  piece  with  the  frame. 

The  armature  is  cj’lindrical  in  form,  and  its  iron  core  is  built  up  of  a series  of  iron 
disks  placed  side  by  side,  but  separated  slightly  from  each  other.  This  construction 
is  shown  in  the  cuts  on  page  lO,  in  which  also  a single  disk  is  shown. 

In  this  way  the  armature  core  is  split  up  into  a large  number  of  separate  sections 
insulated  from  each  other  by  air  spaces  at  every  point  (except  very  near  the  center). 


riie  W'csion  i )ynanio- I'^lcLti  ic  Macliiuc.

By  this  peculiar  construction  of  the  armature,  induced  currents  in  the  core  are  almost 
entirely  prevented,  and  the  loss  of  energy  and  consequent  injurious  heating  of  the 
core,  so  common  in  other  dynamo-electric  machines,  is  entirely  avoided. 

In  order  to  still  further  increase  the  efficiency  of  the  machine,  the  armature  is  con- 
structed to  operate  as  a fan  or  blower  to  produce  a rapid  circulation  of  air  from  the 
center  to  the  periphery,  through  the  sectional  core,  thus  cooling  the  conductors  on 
the  armature,  and  keeping  their  resistance  much  lower  than  would  be  the  case  if  this 
method  of  construction  were  not  used.  The  coils  are  wound  lengthwise  of  the  arma- 
ture, and  connected  to  the  commutator  at  the  end.  The  complete  armature  is  shown 
in  the  cut  below.  By  the  peculiar  winding  of  the  coils  on  the  armature,  and

their  connection  with  the  commutator,  the  highest  possible  efficiency  is  secured,  and 
the  coils  arc  so  perfectly  balanced  electrically  that  the  spark  on  the  commutator  is 
hardly  appreciable. 

Owing  to  the  rigidity  of  the  bearings  and  general  excellence  of  design  and  work- 
manship, the  armature  can  be  revolved  between  the  poles  with  an  extremely  slight 
clearance  — a condition  very  favorable  to  high  efficiency. 

The  coils  exciting  the  field  magnets,  instead  of  being  placed  in  the  main  circuit  in 
the  usual  way,  arc  placed  in  a branch  or  derived  circuit  of  high  resistance,  and  only  a

running 


very  small  fraction  of  tlie  entire  current  passes  tlirough  tliem.  Great  advantaf^es  are 
secured  by  this  arrangement  of  tlie  field  coils.  Less  current  energy  is  expendetl  in 
sustaining  the  field,  the  current  is  more  steady,  and  the  machine  more  uniform  in 
its  operation;  it  is  impossible  to  injure  the  armature  by  short  circuiting  the  main  cir- 
cuit, and  a perfect  and  extremely  economical  system,  of  regulation  can  readily  be 
applied. 

The  regulator  is  shown  in  the  cut  on  this  page.  It  consists  of  a rheostat  or 
adjustable  resistance  placed  in  the  field  circuit.  This  is  inclosed  in  a box,  and  is 
operated  by  a handle  outside,  as  shown  in  the  cut.  It  may  be  placed  in  any  con- 
venient position,  either  near  the  machine  or  at  a considerable  distance  away.  By 
simply  turning  the  handle  of  the  regulator,  the  machine  may  be  adjusted  to  run  any 
number  of  lights  from  one  up  to  the  full  number  it  is  capable  of  running. 

All  other  methods  of  regulation  which  have  been  applied  to  machines  for 
arc  lights  have  proved  so  objectionable  in  practice 
that  they  have  been  but  little  used.  They  have  so 
disturbed  the  electrical  balance  of  the  machine  as 
to  produce  a very  injurious  spark  on  the  commu- 
tator with  less  than  the  full  complement  of  lights  in 
circuit,  and  the  consumption  of  power  has  not  been 
reduced  at  all  in  proportion  to  the  number  of  lights 
cut  out.  With  this  method  of  regulation,  however, 
the  operation  of  the  machine  is  as  perfect  with  one 
light  in  circuit  as  wfith  the  full  number,  and  the  con- 
sumption of  pow'er  is  at  all  times  very  nearly  pro- 
portional to  the  number  of  lights  in  use.  A device 
for  accomplishing  the  same  result  automatically  is 
now'  in  the  works. 

The  efficiency  of  this  machine  is  extremely  high. 

Recent  tests  have  shown  that  over  NINETY  PER 
CENT,  of  the  power  applied  at  the  driving-pulley 
is  available  as  useful  current  in  the  working  or  lamp  circuit, 
the  market  approaches  this  degree  of  efficiency. 

We  make  machines  of  this  type  of  various  sizes,  for  running  from  one  to  thirty 
arc  lamps  in  the  same  circuit.  Machines  of  larger  sizes  are  in  course  of  construc- 
tion, and  will  soon  be  ready. 

Attached  to  all  our  derived  circuit  machines  is  a device  for  preventing  shocks 
and  sparks  while  establishing  or  breaking  connection  between  the  machine  and  the 
field  conductors.  This  device  consists  of  a coil  of  high  resistance  in  the  field  circuit, 
in  combination  with  a switch,  w'hich,  when  closed,  cuts  out  the  resistance  coil.  On 
opening  the  switch  when  the  machine  is  in  operation,  the  current  is  reduced  to  such 
an  extent  that  the  line  connection  may  be  broken  without  the  least  danger  to  the 
machine  or  to  the  person  operating  it.

located  in  a casing  above  the  arc,  and  works  on  substantially  the  same  principle  in  all.

The  lamp  shown  at  tlic  left,  on  pa^^c  12,  is  a plain,  o])en-framc  Weston  lamp.  At  the 
right  is  shown  a duplex  lamp.  In  this  there  are  two  sets  of  carbons  so  arranged  that, 

when  the  first  set  is  consumed,  the  second 
set  is  automatically  brought  into  operation.

and  the  feeding  mechanism  is  at  the  same  time  transferred  to  them.  Lamps  of  this 
type  burn  from  sixteen  to  eighteen  hours  without  renewal  of  the  carbons.  In  all 
these  lamps  the  frame  is  made  of  brass  and  iron,  and  all  the  electrical  connections  are

THE  UNITED  STATES  ELECTRIC  LIGHTING  CO. 


placed  inside  of  the  frame  and  thoroughly  insulated  from  it.  On  page  13,  at  the 
left,  is  shown  an  ornamental  lamp  for  use  in  stores,  hotels,  offices,  and  like  places. 
On  the  same  page  at  the  right  is  shown  an  inclosed-frame  lamp  especially  adapted 
for  out-of-door  use.  The  globe  is  suspended  from  the  casing  containing  the  feeding 
mechanism  by  means  of  a tubular  support  which  incloses  the  upper  carbon  and 

the  electrical  connections.  By 
this  construction  all  the  working 
parts  of  the  lamp  are  entirely  in- 
closed and  thoroughly  protected 
from  the  weather,  the  arc  also  is 
completely  inclosed,  and  more 
perfect  insulation  is  secured,  both 
of  the  electrical  connections  and 
of  the  carbons  themselves,  than 
is  attainable  by  any  other  con- 
struction. The  same  style  of  frame 
may  be  used  for  duplex  lamps. 

These  lamps  are  especially  de- 
signed for  series  lamps,  as  the 
feeding  mechanism  of  each  lamp 
is  entirely  independent,  in  its  op- 
eration, of  that  of  other  lamps  in 
the  same  circuit.  They  work 
equally  well,  however,  as  single 
lamps. 

For  use  with  reflectors  in  steam- 
boat and  head-light  projectors  and 
the  like,  we  make  a focusing  lamp 
shown  in  the  cut  on  this  page.  In 
this  lamp  both  carbons  are  mov- 
able, and  their  relative  rates  of 
movement  are  so  adjusted  that 
the  arc  is  maintained  at  a fixed 
point. 

The  feeding  mechanism  of  the 
Weston  lamp  is  simple  in  construc- 
tion, and  extremely  sensitive  and 
certain  in  operation.  It  maintains 
the  proper  adjustment  of  the  car- 
bon points  with  almost  mathe- 
matical precision,  and  responds 
immediately  to  the  slightest 
fluctuations  in  the  strength  of  the 
Focusing  Lamp.  Current.

T'l'^mCN  lamps  are  run  in  scries,  two  different  forms  of  automatic  cut-out  are 
' ' used  with  each  lamp  for  shunting  the  lamp  out  of  circuit,  in  case  the  feed- 
ing mechanism  should  for  any  reason  fail  to  act.  One  of  these  consists  of  an 
electro-magnet  placed  in  the  circuit  of  each  lamp,  and  so  arranged  as  to  close  a 
shunt  about  the  lamp  whenever  the  circuit  through  it  is  for  any  reason  interrupted, 
thus  preventing  the  extinguishing  of  the  other  lamps  in  the  series.  The  other  form 

of  automatic  cut-out  (shown  in  the  cut  on  this  page) 
is  especially  designed  to  prevent  any  injurious  elonga- 
tion of  the  arc  through  failure  of  the  feeding  mechan- 
ism to  work  properly.  It  consists  of  a spring  switch 
normally  held  open  by  a small  plug,  made  of  an  alloy 
which  fuses  at  a very 
low  temperature.  This 
plug  is  placed  near 
the  upper  carbon,  but 
at  a sufficient  dis- 
tance above  the  arc 
to  prevent  its  melting 
when  the  arc  is  of 
normal  length.  If, 
however,  the  feedin 
mechanism  fails 
act,  the  arc  becomes 
elongated  as  the  car- 
bons burn  away,  and 
the  great  increase  of 
heat  melts  the  fusible 
plug,  allowing  the 

switch  to  close  and  cut  the  lamp  out  of  circuit.  The 
cut-out  may  be  again  adjusted  by  opening  the  switch 
and  inserting  another  fusible  plug.  A top  view  of  the 
fusible  plug,  and  the  jaws  holding  it,  is  given  in  the 
lower  part  of  the  cut,  at  the  right.  This  device  has  been  found  far  more  effective 
and  reliable  in  operation  than  any  other  form  of  cut-out  now  in  use,  but,  owing  to 
the  simplicity  and  certainty  of  action  of  the  Weston  feeding  mechanism,  it  is  rarely 
brought  into  action  in  practice.

cuts  below  show  projectors  for  use  on  steam-boats  and  steam-ships. 

-1-  The  Ocean  Projector  consists  of  a parabolic  reflector  mounted  upon  trunnions 
and  a swivel  in  such  a manner  that  it  can  be  readily  turned  in  any  direction,  cither 
horizontally  or  vertically.  It  is  fitted  with  a powerful  focusing  lamp,  and  projects 
a very  intense  beam  of  light  for  a long  distance.  This  has  been  in  use  for  a long 


time  on  ocean  steam-ships,  and  has  been  found  to  be  of  gjeat  service  in  navigation. 
The  lamp  can  be  readily  removed  from  the  frame  for  use  on  the  vessel  or  about  the 
dock,  in  loading  or  unloading.  The  River  Projector,  as  shown  by  the  cut,  is  of  a 
somewhat  simpler  and  cheaper  form. 


THE  INCANDESCENT  LIGHT. 

IN  the  character  and  quality  of  the  light  produced  the  incandescent  system  is  the 
most  perfect  means  of  artificial  illumination  yet  devised.  In  this  system  the 
light  is  produced  by  the  incandescence  of  a slender  carbon  conductor  inclosed  in  a 
vacuum  in  a small  glass  globe,  and  is  absolutely  steady  and  uniform.  The  incandes- 


18 


THE  UNITED  STATES  ELECTRIC  LIGHTING  CO. 


cent  light  has  all  the  advantages  of  the  arc  light  in  safety  and  convenience,  and  is 
superior  in  steadiness  and  color,  and  more  soft  and  agreeable  to  the  eye.  This  system 
is  especially  adapted  for  interior  illumination  where  comparativ'ely  small  lights  are 
required,  as  it  admits  of  indefinite  division  and  distribution  of  the  current.  Although 
it  has  not  the  capacity  of  the  arc  system  for  producing  large  lights,  and  is  greatly 
inferior  to  it  in  economy,  the  incandescent  light  has  already  demonstrated  its  ability 
to  coDipctc  successfully  with  gas  and  other  systems  of  lighting,  in  many  places,  and  is 
destined  in  the  near  future  to  supplant  gas  for  purposes  of  general  interior  illumination. 


OUR  INCANDESCENT  SYSTEM. 


IN  this  system  the  IVcslou  Dynamo- Electric  Machine  and  the  Maxim  ineandeseent 
lamp  are  used.  The  Weston  machine  for  incandescent  lighti  ng  is  in  its  general 
construction  similar  to  that  already  described  for  arc  lighting,  but  the  winding  of  the 
armature  and  field  magnets  is  somewhat  modified  for  producing  the  different  quality 
of  current  required.  One  very  novel  and  important  feature  of  this  machine  is  its 
capacity  for  self-regulation.  As  the  number  of  lights  in  circuit  varies,  it  is  necessary 
to  v^ary  the  quantity  of  the  current  generated  in  order  to  prevent  accidents  to  the 
lamps,  and  to  keep  them  at  a uniform  brilliancy.  This  has  been  accomplished  in 
other  systems  by  manual  adjustment  of  the  machine  from  time  to  time  by  an  at- 
tendant. This  is  obviously  objectionable,  as  it  involves  the  presence  of  an  attendant 
at  the  machine,  and  accidents  may  occur,  and  in  fact  do  occur  in  practice,  from  lack 
of  attention.  Mr.  Maxim  has  devised  an  ingenious  regulator  for  accomplishing  this 
result  automatically,  which  has  attracted  much  attention  and  works  well  in  practice. 
Mr.  Weston,  however,  has  been  able,  by  a peculiar  construction  of  the  machine  itself, 
to  make  it  entirely  self-regulating  without  the  use  of  any  special  mechanism.  This 
operates  with  such  quickness  and  precision,  that,  with  one  h;mdred  lights,  for  example, 
in  circuit,  ninety-nine  may  be  instantly  turned  out  without  affecting  the  brilliancy 
of  the  remaining  light,  and  without  any  change  in  the  adjustment  of  the  machine. 
'Phis  is  the  only  machine  ever  produced  ivhieh  aceomplishes  this  most  desirable  result. 
In  cases  where  it  is  desirable  to  vary  the  illuminating  power  of  the  lamps,  a regulator 
similar  to  that  used  with  the  arc  machines  is  supplied.  This,  however,  is  not  used 
where  the  lights  are  always  run  at  the  same  candle-power.  The  efficiency  of  this 
machine  is  even  higher  than  that  of  the  arc  machine  of  the  same  type,  and  it  is  in  all 
respects  far  superior  to  any  other  machine  in  the  market. 

The  Maxim  incandescent  lamp,  which  is  shown  full  size  in  the  cut  on  the  next 
j)age,  consists  of  an  M-shaped  carbon  conductor,  inclosed  in  a vacuum  by  a glass 
globe  about  two  and  one-half  inches  in  diameter.  The  carbon  is  made  by  a peculiar 
process  devised  by  Mr.  Maxim,  which  gives  it  very  great  durability,  strength,  and

THE  UNITED  STATES  ELECTRIC  LIGHTING  CO. 


capacity  for  withstanding  the  disintegrating  effect  of  powerful  currents.  One  of  the 
Maxim  lamps,  constructed  to  give  a light  of  twenty-five  candles,  was  run  for  a short 
time  at  the  Paris  Exposition  at  an  illuminating  power  of  eleven  hundred  candles.  We 
do  not  believe  that  an\'  other  incandescent  lamp  would  stand  such  a test.  The  life- 
time of  the  Maxim  lamp,  when  run  at  its  normal  power,  is  very  long.  In  plants  which 
have  been  erected  during  the  past  year  the  average  lifetime  of  the  lamps  has  been 
considerably  over  a thousand  hours,  and  many  lamps  which  have  been  burning  from 
two  to  three  thousand  hours  are  still  intact. 

A d}'namo-machine  and  ninety-seven  lamps  were  started  in  the  New-York 
General  Post-Office  on  March  13,  1882.  Since  that  time  the  machine  has  been 
running  one  hundred  and  forty  hours  per  week  without  repairs  or  an  accident,  and  on 
September  ist,  1882,  the  average  record  of  the  lamps  was  eighteen  hundred  and  fifty 
hours  each.  There  were  fifteen  lamps  which  had  burned  continuously  thirty-four 
hundred  and  fifty-six  hours  each,  and  were  still  in  good  condition. 

A dynamo  and  fifty-six  lamps  were  placed  on  the  ferryboat  Jersey  City  of  the 
Pennsylvania  R.  R.  Co.,  in  November,  1881.  On  August  29th,  1882,  the  plant  had 
been  in  actual  operation  sixteen  hundred  and  forty-five  hours,  and  the  average 
lifetime  of  the  lamps  was  sixteen  hundred  and  nine  hours  each. 

Our  incandescent  system  was  the  first  one  ever  put  into  practical  commercial  use. 
It  was  first  introduced  in  the  early  fall  of  1880,  and  has  been  in  constant  use  since 
that  time  in  the  vaults  of  the  Mercantile  Safe  Deposit  Co.,  No.  120  Broadway,  N.  Y., 
in  the  New-York  Stock  Exchange,  and  other  places.  A large  number  of  plants 
have  since  been  erected,  all  of  which  are  giving  perfect  satisfaction : among  the 
places  where  such  plants  are  in  operation  in  New-York  City  may  be  mentioned  the 
Hoffman  House,  the  St.  Nicholas  Hotel,  the  National  Park  Bank,  the  Post-Office, 
and  Washington  Market.  The  names  of  other  parties  using  this  system  will  be 
found  among  the  references  at  the  end  of  this  pamphlet. 

We  manufacture  incandescent  lamps  of  different  sizes,  for  giving  a light  of  eight 
caiulles  and  upward.  Each  lamp  is  provided  with  a socket  or  holder,  as  shown  in 
the  cut  on  page  19,  which  is  so  arranged  that  the  lamp  when  in  position  is  held 
firmly,  but  may  be  readily  removed  for  renewal  ; and  merely  placing  the  lamp  in  the 
holder  makes  the  necessary  electrical  connections.  These  holders  are  made  with  or 
without  switches,  or  keys  for  turning  the  light  on  and  off,  and  of  various  styles,  plain 
and  ornamental.  Eor  use  with  chandeliers  and  in  similar  places,  it  is  frequently  desir- 
able to  have  the  switch  separate  from  the  holder,  and  in  a more  accessible  and  con- 
venient place  : and  a single  switch  will  frequently  suffice  for  all  the  lights  on  a 
chandelier.

manufacture  and  furnish  a variety 
of  fixtures  for  mounting  the  different 
parts  of  the  apparatus.  These  vary  accord- 
ing to  the  different  circumstances  under 
which  the  apparatus  is  to  be  used.  Among 
them  may  be  mentioned  the  following : 

In  the  cut  on  page  2i  is  shown  a supple- 
mentary base  for  the  machine.  This  is  made 
of  hard  wood,  and  may  be  constructed  of 
any  convenient  height.  The  machine  is 
mounted  upon  a sliding  platform  adjusted 
by  means  of  a sirew  shown  at  the  right. 
By  means  of  this  screw  the  belt  may  be 
tightened  or  loosened  at  will  while  the 
machine  is  running.  This  is  a very  desir- 
able feature,  as  it  entirely  does  away  with 

the  necessity  for 
stopping  the  ma-

be  necessary  to 
tighten  or  slacken

cording to  the  current  they  are  designed  to  carry.  Owing  to  the  fact  that  the  alloy 
used  fuses  at  so  low  a temperature,  the  drops 
of  melted  metal  cannot  ignite  the  most  in- 
flammable material.

of  sheet-iron,  and  tlioroughly  protects  the  lamp  from  the  weather,  and  at  the  same 
time  serves  as  a reflector.  This  may  be  applied  to  any  form  of  lamp-post. 

When  desirable,  we  furnish  a pulley-support  for  mounting  arc  lamps,  so  arranged 
that  the  lamp  may  be  readil)’  raised  or  lowered  without  inttn'fering  with  the  light. 

For  incandescent  lamps  ordinary  gas-fixtures  may  be  used  by  properly  attaching 
the  lamp-holders,  anti  the  conducting  wires  may  be  carried  to  the  lamps  either  through 
the  pipes  or  alongside  of  them.  We  manufacture,  however,  a variety  of  special  fix- 
tures for  incandescent  lamjis. 

The  illustration  below'  represents  an  ornamental  bracket  designed  for  incandescent 
lamps.  It  is  so  arrangetl  that  it  may  be  swung  from  side  to  side  when  the  current  is 


on,  without  in  any  way  affecting  the  light.  It  can  be  taken  down  b}-  merely  loosen- 
ing a thumb-nut  and  lifting  the  bracket  from  its  wall-plate.  I'his  wall-plate  contains 
a safet}’  device  of  the  same  character  as  those  shown  on  page  22,  placed  in  the  lamp 
circuit,  which,  in  case  of  any  abnormal  flow  of  current,  interrupts  the  circuit,  and  so 
preserves  the  lamp  from  injury. 

In  the  cut  on  the  next  page  is  shown  a neat  and  simple  fixture  specially  designed 
for  use  in  factories,  for  supporting  tw'o  incandescent  lights.  The  conducting  wires 
pass  down  inside  of  the  fixture,  and  branch  off  on  each  side  to  the  lamps  which 
are  arranged  under  opal  reflectors. 

We  furnish  fixtures,  plain  and  ornamental,  for  any  desired  number  of  lights 
embodying  these  and  other  improvements,  which  specially  adapt  them  to  our  system.

ERECTION  OE  AI'I’ARATUS. 

'I'\  furnish  line  wires  and  all  necessary  material  for  the  erection  of  electric  light- 
' > ing  plants  sold  by  us,  at  current  market  rates.  All  our  electric  lighting 
apparatus  has  been  approved  by  the  New  York  Board  of  Fire  Underwriters,  and  we 
have  taken  pains  even  to  go  far  beyond  their  requirements  in  securing  absolute  safety, 
both  in  the  construction  of  the  apparatus  and  in  its  erection. 

We  prefer,  in  all  cases,  to  send  competent  and  experienced  men  from  our  factory 

to  superintend  the  erection  of  plants  which  we 
sell,  charging  only  the  time  and  actual  expenses 
of  the  men  so  engaged.  Where  this,  however, 
is  not  practicable,  we  furnish  explicit  rules  for 
the  erection  of  the  apparatus,  and  insist  that  the 
purchaser  shall  agree  to  comply  with  them. 

CENTRAL  STATIONS. 

OUR  systems  of  lighting  are  w'ell  adapted 
for  furnishing  lights  from  central  stations, 
and  many  of  our  local  companies  are  doing  a 
large  business  in  the  rental  of  lights  furnished 
in  this  way.  The  cuts  on  pages  26  and  27  are 
views  of  a station  erected  by  the  Newark  Electric 
Light  and  Power  Company,  at  Newark,  N.  J. 
This  company  Avas  organized  in  March,  1882, 
and,  within  six  months,  was  running  upwards  of 
three  hundred  arc  lights 
from  its  station,  and  or- 
ders for  additional  lights 
were  received  faster  than 
they  could  be  supplied. 

The  United  States  Il- 
luminating Company  has 
Iwo-light  Factory  Fi.xture.  upwards  of  SIX  hundred 

arc  lights  in  operation 

from  different  stations  in  New-York,  besides  a large  number  of  incandescent  lights. 
The  New  ICngland  Weston  Electric  Light  Company  has  about  three  hundred  lights 
running  in  Boston.  The  Rochester  lilcctric  Light  Company  has  about  one  hundred 
and  fifty  lights  running  at  Rochester.  The  Citizens’  Pdectric  Light  Company  has 
a large  number  of  lights  running  at  Toledo,  O.,  and  various  others  of  our  local  com- 
IRinies  have  similar  stations. 

We  build  special  machines  and  lamps  for  lighting  by  the  mast  or  tower  system,  in 
places  where  this  system  can  be  used  to  advantage.

rior to  all  other  machines  in  the  market.  ,Mr.  W^cston’s  lony;  experience  in  electro- 
mctallur^)’  has  enabled  him  to  adajit  the  machine  very  perfectly  to  the  practical 
requirements  of  the  business.  It  is  very  efficient  in  operation,  strongly  built,  and  will 
stand  a great  deal  of  hard  usage.  It  needs  no  special  skill  for  its  proper  management. 
A peculiar  feature  of  this  machine,  of  great  value,  is  the  automatic  switch  for  prevent- 
ing a reversal  of  the  polarity  of  the  machine.  As  is  well  known,  an  electro-depositing 
bath  acts  as  a battery  tending  to  produce  a current  in  an  opposite  direction  to  the 
current  from  the  machine  ; when  the  machine  stops,  or  any  accident  happens  to  it 
by  which  its  electro-motive  force 
is  reduced  below  the  electro- 
motive force  at  the  electrodes  of 
the  bath,  a current  flows  back 
through  the  field  magnets  of  the 
machine  and  reverses  their  polarity, 
and  upon  again  starting  the  ma- 
chine the  direction  of  the  current 
is  reversed,  thus  removing  the  de- 
posit from  the  articles  in  the  bath, 
and  in  many  instances,  if  not  ob- 
served in  time,  destroying  them 
and  seriously  injuring  the  solution. 

The  automatic  switch  or  cut-off 
used  with  this  machine,  which  is 
shown  in  the  lower  right-hand 
corner  of  the  cut,  entirely  prevents  this,  as  it  cuts  the  machine  out  of  circuit  upon  any 
considerable  diminution  of  speed.  W'e  shall  shortly  publish  a special  catalogue  of  this 
apparatus. 

EI.F.CTRIC  MOTORS.

Gentlemen : — \\'e  have  been  using  four  of  your  ten-light  machines  for  nearly  one  year,  and 
find  them  to  work  in  the  most  satisfactory  manner. 

W'e  find  the  lights  not  only  very  powerful,  but  steady;  the  color  perfectly  white,  which  makes 
it  very  agreeable  to  our  employees.  We  find  it  particularly  adapted  to  our  work  of  all  classes, 
machine-rooms,  foundries,  paint  and  ornamental  room,  as  also  for  office  use.  In  fact,  we  would 
not  be  without  them.  Another  great  point  about  them  to  be  considered  is,  the  machines  can  be 
operated  by  the  same  engines  in  conjunction  with  other  machinery.

Gendcmen  : In  reply  to  your  favor  asking  if  the  lights  you  put  in  for  us  are  still  giving  satis- 
faction, would  say : We  have  used  a forty-light  plant  in  our  establishment  for  the  past  twelve 
months,  with  the  most  pleasing  satisfaction.  Your  light  has  proven  even  more  satisfactory  than 
you  claimed  for  it.  During  the  whole  time  of  its  use  we  have  had  no  trouble  or  mishap.  We 
now  contemplate  enlarging  our  premises,  and  ivill  want  some  twenty  lights  more. 

Our  gas-bills  for  the  year  previous,  in  the  smaller  house,  ran  as  high  as  $4,000.00  per  annum. 
By  actual  estimate  the  expense  of  illuminating  the  present  premises  (more  than  double  as  large) 
will  not  exceed  $3,500.00  jier  year. 

We  are  more  than  pleased  with  the  result  of  your  light,  and  would  not  jiart  with  it  under

we  could  not  think  of  getting  along  without  it.  The  light  is  satisfactory  in  every  way,  and  from 
our  observation  of  other  electric  lights,  since  introduced  here,  we  consider  ours  the  best  light.

Ofkice  of  the  Iron  Steamboat  Company. 

New-York,  August,  3,  1881. 

The  United  States  Ph.ectric  Lighiing  Company,  120  Broadway,  City. 

Gentlenicn : We  had  one  of  the  ten-light  Weston  machines,  with  engine  complete,  put  on  our 
steamer  Cetiis,  at  the  same  time  we  were  using  the  Brush  Light  on  our  pier. 

The  success  attending  the  lighting  of  this  first  steamer  was  so  great  that  we  decided  at  once 
to  light  the  remaining  boats  which  we  had  contemplated ‘lighting,  namely,  the  Taurus,  Pegasus, 
and  the  Cepheus. 

The  color  of  your  light  is  remarkable  for  its  purity  and  absence  of  any  blue  shade  peculiar  to 
all  others.  The  boats  are  subject  to  jjretty  rough  handling  in  a heavy  sea,  yet  the  lights  run 
with  perfect  steadiness. 

.\lthough  the  lights  are  necessarily  hung  quite  low,  the  porcelain  globes  which  your  company 
have  provided  produce  an  effect  unequaled  by  any  other  means  of  illumination. 

The  engine  furnishing  the  lights  is  frequently  run  with  15  or  20  lbs.  steam-pressure,  showing 
the  economy  in  the  jiower  consumed  in  your  system. 

W'e  think  that  your  light  is  well  adapted  to  the  illumination  of  every  class  of  river  and  ocean 
steamers. 

Yours  truly, 

CiEO.  S.  Scott,  President.

four  additional  lights  (with  necessary  engines  for  running  the  same),  for  use  upon  our  three

'I'liK  Umtkd  States  Ki.ectkic  Lichting  Co. 

Gentlemen : I was  the  first  to  introduce  the  electric  liglit  in  iny  line  of  busine.ss.  1 am  glad 
to  have  the  ojjportimity  of  testifying  as  to  its  efficiency  and  economy. 

In  April,  1878,  I contracted  with  your  company  for  six  dynamo-machines  and  twelve  lamps, 
which  pnrved  so  satisfactory  that  I have  since  increased  the  number  to  twelve  machines  and 
twenty-four  lamps. 

The  light  enables  my  customers  to  distinguish  a difference  in  the  .shade  of  color  in  goods  as 
easily  by  night  as  in  daylight,  and  I have  always  been  pleased  with  it  on  the  score  of  economy, 
cleanliness,  and  freedom  from  smoke  and  bad  odors  from  gas. 

Respectfully,

New- York,  December  17,  1881. 

The  Uniied  States  Electric  Lighting  Co. 

Gentlemen  : T have  in  use  at  each  of  my  theaters  thirteen  of  your  electric  lights,  and  am  highl\- 
pleased  with  the  satisfiiction  they  have  afforded,  not  only  to  those  connected  with  the  theatres, 
but  to  the  public  as  well. 

At  the  time  I exjierimented  with  the  lights  for  theater  purposes,  it  was  generally  siqrposed 
that  they  would  prove  unsuitable  for  the  lighting  of  an  auditorium,  and  that  they  could  not  be 
utilized  to  the  same  extent  as  gas.  I am  happy  to  be  in  a position  to  state  that  all  the  objec- 
tions urged  against  their  use  in  theatres  have  proved  unfounded,  and  that,  at  a great  saving  of 
expense  and  labor,  they  furnish  a much  superior  light  to  any  obtainable  under  the  old  system. 

1 congratulate  you  upon  the  improvements  you  have  introduced,  and  look  for  the  time  when 
you  will  have  reached  that  jierfection  which  will  in  itself  commend  your  lights  to  general  use. 
Until  you  reach  that  position,  you  can  make  free  use  of  my  name  and  theaters  as  a guaranty 
that,  in  your  “ electrics,”  managers  and  proprietors  of  places  of  public  amusement  will  find  the 
cheapest  and  best  illuminating  power  for  their  purposes. 

Yours,  very  truly, 

Harry  Miner.

Gentlemen  : The  work  of  erecting  and  putting  in  running  order  our  electric  lighting  jilant, 
begun  by  Mr.  Young,  has  just  been  completed  by  Mr.  Erank  Badt,  and,  on  the  eve  of  the  latter 
gentleman’s  departure,  I take  the  opportunity,  and  with  great  jileasure  in  so  doing,  to  testify  to 
the  excellent  workmanship  displayed  by  both  gentlemen.  Our  plant  of  four  machines  and  forty 
lamps  is  now  entirely  in  operation  and  giving  the  most  satisfactory  results.  Everything  does 
just  what  was  claimed  for  it,  and  the  general  excellence  of  the  plant  is  due,  I think,  in  a large 
measure  to  the  careful  and  workmanlike  manner  in  which  it  was  put  together,  and  the  great 
attention  paid  to  the  slightest  details.  It  gives  me  pleasure  to  add  my  testimonial  of  the  excel- 
lence of  your  lighting  system,  and  we  regard  ourselves  as  fortunate  in  its  possession.

steady,  safe  to  the  eyes,  and  our  workmen  are  delighted  with  the  change  from  gas  and  kerosene. 

We  have  twelve  lights,  and  light  up  our  entire  factory  at  an  estimated  cost  of  $2.50  per

winter,  we  have  to  say  we  are  well  satisfied  with  the  operation  of  the  “ plant,”  both  in  quality 
and  cpiantity  of  light  obtained;  it  comes  fully  up  to  your  repre.sentations.  The  light  given  is 
white,  clear,  and  steady.  It  is  easily  managed  by  our  mechanic,  who  has  had  no  jirevious  experi- 
ence in  such  matters. 

VV'e  do  not  feel  the  extra  power  required  for  these  lights  ; we  may  use  a little  more  fuel,  but 
the  increased  consumption  is  so  small  an  amount  that  it  is  hardly  iierceptible.

Weston  Electric  Light. 

For  two  seasons  I ha\-e  lighted  the  grounds  of  the  “ Oakland  Garden  ” with  your  light, 
using  ten  lamps.  The  electric  lights  have  added  largely  to  the  attractiveness  of  the  Garden,

Gentlemen : W'e  have  had  in  use  for  some  months  in  our  restaurant  a ten  and  a five-light 
Weston  Electric  Light  Machine,  the  ten-light  purchased  after  a trial  of  the  five-light,  and  after  a 
trial  of  other  electric  lights. 

W'e  run  the  five-light  during  the  day-time,  and  the  ten-light  all  night. 

Our  gas-bills  are  $85  less  weekly  than  during  the  corresponding  week  last  year,  and  the  cost  of 
electric  lighting  is  simply  the  five  horse  [lower  used  during  the  day,  and  about  eight-horse  power 
at  night,  with  the  carbons,  thus  showing  a net  saving  of  nearly  $85  per  week,  with  the  advantage 
of  a steady,  pleasing,  white  light,  that,  notwithstanding  rather  low  ceilings,  gives  the  greatest  satis- 
faction to  our  guests,  numbering  over  5,000  daily. 

The  heat  from  the  gas  necessitated  the  constant  use  of  revolving  fiins,  that  increased  the 
trouble  by  blowing  the  heat  down  on  the  tables. 

The  care  of  the  lights  is  in  the  hands  of  one  of  our  regular  help.

our  works  in  South  Boston,  I am  much  pleased  with  its  use.  The  steadiness  of  the  light  seems 
perfect,  and  the  splendid  illuminating  ciuality  renders  our  yard  and  its  surroundings  as  light  as

Dear  Sir : The  lights  you  put  in  at  the  mills  of  the  Lowell  Carpet  Co.  give  great  satisfac- 
tion. I saw  them  one  evening  last  week,  and  I never  saw  any  better  lights.  They  are  very 
steady  and  clear.  Colors,  of  course,  are  distinguished,  as  they  cannot  be  under  the  gas-light, 
and  some  work  is  now  carried  on  by  the  electric  light  which  before  could  only  be  done  by 
daylight. 

Yours  truly,

Gentlemen  ; M'e  have  forgotten  the  size  or  number  of  the  Weston  Dynamo-Electric  Machine 
that  we  have  in  use  to  light  our  works,  for  manufacturing  the  Leffel  Turbine  \\’ater-AVheel  and

fectly satisfied  with  the  (juality,  whiteness,  and  steadiness  of  the  light,  and  we  believe  there  will 
be  no  occasion  to  use  more  than  the  five  lights, — two  in  the  foundry  and  three  in  the  machine- 
shop.  W’e  had  engaged  originally  of  you  a larger  machine  and  more  lamps,  but,  as  we  now  feel, 
and  so  far  as  our  experience  goes,  don’t  think  that  it  will  be  necessary  to  change  to  the  larger 
size,  this  having  been  put  in  temporarily  to  supply  us  until  the  larger  one  wtts  completed.  AVe 
could  not  be  induced  to  use  gas  or  any  other  kind  of  light  as  long  as  this  holds  out  so  well.

The  contrast  between  the  color  of  your  lights  and  others  in  use  in  this  city  is  greatly  in  your 
favor.  'I'hey  are  white  and  steady,  resembling  sunlight  more  than  anything  else.  ^Ye  are  run-

Gentlemen  ; We  purchased  one  of  your  ten-light  machines  after  our  Mr.  F'.  Smith  had 
thoroughly  investigated  all  the  different  electric  light  systems  in  use  in  and  about  New  York. 

We  had  noticed  a peculiarity  in  the  whiteness  of  your  light,  and  we  now  find,  after  running 
them  for  some  time,  that  they  are  by  far  the  most  economical  in  power  consumed,  and  in  the 
(juality  of  the  light  produced,  of  anything  that  we  have  yet  seen. 

We  are  using  a comparatively  small  engine  and  boiler  for  running  them,  which  gives  us  an 
opportunity  of  judging  of  the  co.st  of  the  light,  ^\'e  find  it  a great  improvement  over  gas,  which 
we  have  entirely  discontinued,  and  it  gives  our  customers  the  advantage  of  selecting  goods  bv 
night  as  well  as  by  bright  sunlight,  thus  nearly  doubling  the  hours  in  which  we  can  sell  goods. 
^\'e  have  no  hesitation  in  saying  that  your  system  is  by  far  the  best  in  use.

Genllemen ; 'I'he  ten-light  \\'eston  machine  and  lamps  that  you  put  in  for  us  some  weeks  ago 
are  running  to  our  comjilete  .satisfaction. 

Having  had  exjierience  heretofore  in  various  electric  lamps,  knowing  the  power  consumed

in  existence  for  electric  lighting. 

'I'he  machine  was  put  up  at  a very  short  notice,  and  is  driven  from  an  ordinary  engine  on  the

we  have  had  no  difficulty  whatever  in  maintaining  the  lights  without  interrujition.

THE  UNITED  STATES  ELECTRIC  LIGHTING  CO. 


One  of  the  ten  lights  I experimentally  had  suspended  from  the  ceiling  of  our  main  par- 
lor, one  of  the  largest  in  the  country,  and  the  result  is  past  all  conception.  It  has  displaced 
forty-two  five-feet  burners  (gas),  giving  a far  steadier,  more  powerful,  and  brighter  light  than  we 
have  ever  had  in  the  same  room. 

We  find  the  color  is  not  at  all  objectionable  to  the  ladies,  the  complexion  remaining  the  same 
in  the  light,  unlike  all  other  electric  lights  that  we  know  of,  that  give  a blue,  ghastly  appearance. 

Regarding  the  relative  cost  as  compared  with  that  of  gas,  a point  I have  hitherto  been  un- 
able to  ascertain,  I can  now  give  correctly,  viz. : six  of  the  ten  lights  now  save  me  thirty-five 
thousand  feet  of  gas  per  week,  w hich,  at  the  price  I pay  for  gas,  viz.,  $3.50  per  thousand,  equals 
a saving  of  $122  per  week,  less  the  cost  of  running  the  entire  ten  lights,  which  is  $40  per  week, 
showing  a net  saving  of  $82  per  week,  with  four  lights  to  spare. 

I am  very  respectfully  yours,

Syracuse,  N.  Y.,  April  20,  1881. 

To  u>hoin  if  may  concern  : At  the  request  of  Mr.  Teall,  we  cheerfully  make  the  following 
statement  as  to  our  experience  with  the  electric  light : Mr.  Childs  and  myself  were  appointed 
by  the  “ Board  of  Directors  ” to  go  to  Xew-York  and  examine  the  different  electric  lights. 

A\'e  did  so,  and  in  our  opinion  the  Weston  light  was  a whiter  light  than  the  Brush.  The 
bluish  tinge,  which  is  characteristic  of  the  Brush  light,  seemed  to  be  absent  from  the  Weston 
light. 

'I’he  power  seemed  to  be  much  less  per  light  with  the  Weston  than  it  did  with  the  Brush, 
from  the  indicator  cards  that  were  taken  from  engines  running  electric  lights  of  both  manu- 
facturers. 

We  have  been  running  the  Weston  light  for  about  two  months,  and  it  has  been  running  very 
satisfactorily,  and  has  not  caused  any  trouble. 

And  we  think  the  estimate  of  three-fifths  of  a horse-power  to  a light  of  a so-called  two 
thousand  candle-power,  would  not  be  out  of  the  way  as  a fair  estimate  of  the  actual  power  when 
in  common  use. 

Yours  truly.

Albany,  N.  Y.,  July  28,  1881. 

To  whoever  it  may  concern  : This  is  to  certify  that  we  have  used  the  Weston  Electric  Light 
Machine  in  our  stores  for  the  past  seven  months,  and  believe  it  to  be  the  best  machine  for  light- 
_ ing  purposes  yet  produced. 

d'his  light  takes  only  about  one-half  as  much  power  to  each  light  as  the  Brush  or  any  other 
machine  that  we  know  of. 

We  were  running  the  Brush  sixteen-light  machine  for  Messrs.  W.  M.  Whitney  &:  Co.  last  fall, 
and,  as  near  as  we  could  ascertain,  it  took  over  twenty  horse-power,  while  the  Weston  would  not 
take  over  ten  horse-jiower  for  the  same  number  of  lights. 

\\'e  also  find  the  Weston  lights  are  much  more  powerful,  and  of  a much  better  color,  and 
steadier. 

Yours  respectfully,

Gents:  The  two  ten-light  machines,  with  twenty  lamps,  you  furnished  us  in  June  last,  for 
our  Park  and  Spring  Pavilions,  we  lused  regularly  without  interruption  during  our  business  season, 
from  July  ist  to  September  18th,  inclusive,  and  have  given  us  entire  satisfaction.  The  lights 
have  been  greatly  admirer!  by  our  r-isitors  and  guests,  who  generally  pronounced  them  superior 
to  all  others  in  the  steady,  white,  diffusive  character  of  the  light.

Gentlemen : Your  favor  of  the  14th  inst.  is  at  hand.  We  have  used  a Weston  light  ma- 
chine for  lighting  the  rajiids  in  the  rear  of  our  house,  with  great  satisfaction  to  the  guests  of 
our  house  and  ourselves.  The  light  was  considered  to  be  very  white  and  remarkably  beautiful, 
and  pure  and  brilliant.  Yours  truly,

G.  Hekari),  Esq.,  President  U.  S.  Electric  Li}:;/iti/ig  Co. 

Dear  Sir : In  answer  to  your  inquiry  if  the  light  we  have  is  an  advantage  to  us,  and  is  what 
you  represented  it,  I would  say,  that  we  formerly  used  gas  in  this  depot,  and  we  have  been  using 
the  electric  light  between  four  and  five  months;  and  I must  confess  that  it  surj)asses  anything  yet, 
and  we  cheerfully  recommend  it  to  all  transjjortation  companies  to  light  their  freightdiouses  or 
docks,  where  they  are  obliged  to  do  much  night-work.  It  facilitates  our  work;  we  can  read  the 
marks  on  freight  packages  the  same  as  by  daylight,  and  we  find  that  there  are  less  errors  than 
formerly. 

We  hold  and  make  business  by  giving  it  (juick  dispatch,  and  \ve  think  that  this  electric  light 
will  assist  us  to  do  this  without  any  e.xtra  expense. 

I remain,  yours  respectfully,

Gentla/icu : In  reply  to  your  inquiry  concerning  the  incandescent  lights  which  you  put  in  the 
vaults  of  the  Stock  Exchange  about  a year  and  a half  ago,  I would  say  they  are  highly  satisfac- 
tory. They  are  perfectly  steady,  and  give  a bright,  yet  soft  and  pleasant  light,  being  superior  to 
gas  not  only  in  this  respect,  but  also  in  the  fact  that  they  do  not  consume  the  oxygen  of  the  air, 
and  produce  no  heat  of  any  consequence. 

Yours  truly, 

Edwin  J.  Coles,  XdYv.

Gentlemen:  We  started  the  machine  on  your  incandescent  system  on  October  10,  1881,  and 
from  that  date  to  January  9,  1882,  they  have  run  238^;^  hours.  We  have  burned  on  the  two  ma- 
chines together  one  hundred  and  seventeen  lamps,  and  have  obtained  I'rom  them  ample  light  for 
four  looms  per  lamp.  During  the  2^8^  hours  eight  of  the  lamps  have  burned  out.  The  light  is 
perfectly  steady,  and,  from  the  ease  with  which  it  can  be  distributed,  and  absence  from  shadows 
and  flickering,  we  consider  it,  for  our  purpose,  much  superior  to  the  arc  light.  It  has  given  us  no 
trouble,  and,  so  far,  we  are  very  much  pleased  with  its  operation. 

\'ery  truly, 

Henry  F.  Lippitt,  Sn/t.

Gentlemen:  In  reply  to  your  inquiry  regarding  your  electric  lights  for  offlce  and  dwelling- 
house,  we  beg  to  say  that  we  have  had  them  in  our  office  for  nearly  a year,  and  that  they  gi\-e 
entire  satisfaction,  so  much  so  that  we  have  had  all  our  gas-pipes  removed.  \\'e  have  in  all 
eleven  burners,  and  the  light  they  give  is  fully  equal  in  brilliancy  and  steadiness  to  the  best  gas, 
and  is  free  from  the  odor,  heat,  and  vitiating  properties  of  the  latter.  It  has  made  a great  differ- 
ence in  the  purity  of  the  atmosphere  and  general  comfort  of  the  office.

Gentlemeu : Vour  favor  of  January  1 ith  received.  **♦**##  T'he  result  at  the 
United  States  Mint,  in  this  city,  is  equally  satisfactory.  The  plant  was  started  on  the  28th 
Xovember.  During  the  month  of  December,  with  sixty-four  lights;  they  ran  222  hours,  during 
which  time  but  one  lamp  gave  out,  from  defective  carbon,  and  this  burned  out  within  an  hour 
from  lighting.  This  will  give  an  average  of  nearly  9 hours  per  night. 

Very  truly  yours.

I'he  Western  Mail. 

Cardiee,  Wales,  August  i,  1882. 

My  Dear  Sir ; Vour  Maxim  Incandescent  lamps  have  given  us  the  greatest  satisfaction. 
.\fter  trying  various  systems  of  electric  lighting  for  our  editorial  office,  case-room,  machine-room, 
etc.,  we  have  arrived  at  the  conclusion  that  your  installation  is  at  once  the  most  efficient  and 
economical  that  we  can  have.  MT  are  able  to  speak  of  it  with  the  more  confidence  as  we  have 
now  (kqiended  upon  this  mode  of  illumination  for  nearly  three  months.  As  regards  comparative 
e.xpense,  1 am  not  in  a position  to  state  exactly  how  the  cost  of  electric  lighting  stands,  as  the 
motive  power  in  our  case  is  already  at  hand.  Put  this  1 will  say,  that  if  the  electric  light  costs 
us  ten,  or  even  twenty,  per  cent,  more  than  we  were  formerly  paying  for  gas,  I would  gladly  pay 
the  difference  to  be  rid  of  the  deleterious  products  of  combustion  which,  under  the  old  system, 
nightly  poisoneil  the  atmosphere  which  newspaper  men  are  unfortunately  compelled  for  so  many 
hours  to  breathe. 

You  may  form  some  idea  of  the  relief  which  the  electric  light  affords  us  when  I tell  you  that, 
tested  by  the  thermometers  we  have  hanging  in  our  various  rooms,  the  temperature  under  that 
system  is  from  ten  to  fifteen  degrees  lower  than  when,  under  precisely  similar  conditions,  the 
gas-lights  are  burning. 

As  a mere  matter  of  health,  the  electric  light  is  bound,  so  soon  as  it  becomes  practically 
available  to  the  iniblic,  to  supersede  every  other  mode  of  illumination. 

My  experience  leads  me  to  believe  that,  under  favorable  circumstances,  it  can  be  produced 
more  cheaiily  than  gas.  As  regards  its  efficiency,  I can  only  say  we  produce  a morning  paper 
by  its  means  every  day,  and  1 shall  be  glad  to  show  it  in  practical  operation,  and  give  every  in- 
formation in  my  jiower  as  to  its  cost,  to  any  one  who  may  take  an  interest  in  the  subject. 

Faithfully  yours,

C.  W.  Heiiard,  Ks(p,  United  States  Electric  Liy^hting  Co.,  120  Broadway,  New-York,  U.  S.  A. 

Dear  Sir : 1 beg  to  acknowledge,  and  thank  you  for,  your  letter  of  the  ist  inst. 

My  directors  are  much  gratified  at  the  results  you  report,  in  the  working  of  the  Maxim  lamps 
on  the  ferry-boat,  as  the  figures  confirm  our  exiierience  with  the  lamps  at  Edinburgh  General 
Lost-office,  where  we  have  had  fifty-one  burning  for  the  past  six  months.  They  also  give  great 
satisfaction  at  the  Glasgow  Fine  .Yrt  Galleries,  the  Norwich  Free  Library,  the  Prince  of  Wales 
I’hcater,  at  Liverpool,  Risca  Colliery  (in  South  Wales),  and  many  other  places.  The  Marquis  of 
Salisbury  is  also  increasing  the  number  he  has  in  use  at  Hatfield  Hou.se.  At  the  recent  royal 
wedding  at  Windsor  the  Maxim  lamps  were  used  for  many  nights  in  the  quadrangle  of  the 
castle,  and  the  Maxim  search-lights  were  also  exhibited  in  use  to  the  Queen. 

'The  double  Weston  lamps  have  been  in  use  some  time  (thirty-two  of  them)  in  Queen  Vic- 
toria street,  in  the  city  of  London,  and  the  general  verdict  on  them  is  that  they  surpass  all  that 
has  been  previously  seen  in  the  way  of  electric  lighting. 

I am  writing  Mr.  Hartley  regarding  the  supply  of  machines,  etc. 

I am,  dear  sir,  yours  faithfully, 

F.  H.  Landon,  Secretary.
